Anyone know if the snowmobile clutches will work on an atv? Mainly the drive clutch.

 

Hey Vig, the taper on any of the clutches after 1980 or so is the same. You can bolt one right up. THE PROBLEM IS: The snow clutches are bigger. Snowmobiles are geared high. The clutches actually start out at about a 4:1 underdrive and attain about a 25% overdrive. Thay can do that because of the clutch sizes. They got the best of both worlds. The atvs are a smaller scale version. Althoug they will bolt up, you can't mix them. Sorry, wont work.Bubba

 

A bud from the Bad Boyz forum has one running. Although he currently runs it w/o the cover (EEEEEEKKK!!!) He's been trying to get a custom unit made. Like Bubba said though, lots of hassles.

Ken, he's not trying to run the primary snow clutch with the atv secondary is he? It would surely try to overshift and break or damage the belt I would think. If he's got the secondary as well, how did he get the keyed clutch adapted to the splined shaft of the atv trans? Bubba

 

Bubba, hey's runnin' the whole shebang....primary and secondary.

Bubba;
The original builder of this bike fabbed a sleeve to convert the rear shaft to sled specs. Also; I've seen quads with sled jack shafts and rear clutch hooked directly to rear wheels via chain and no tranny. Gear reduction was handled with sprockets only.

 

Awesome, It would be a great benefit to run the snow clutches as mentioned before, just not a whole lot of working area there.Bubba

 

Why? If they were superior why arent they normal production. I wouldnt consider putting a 4 wheeler cvt on my sled. just a curious rider.

 

big daddy, the snow clutches are bigger. They offer a lower gear ratio for initial takeoff. You they start shifting out, there is more area, thus more shifting that can occur. They would let you gear higher and still take off great, and if you had the power to pull it on the other end such as a snowmobile, they would attain great top speed as well. You get the best of both worlds. Hope this sheds some light.Bubba
